What is OAuth 1.0 and how does it work? ›

Accessing user data with OAuth 1.0 involves a few requests back and forth between client application, user, and service provider. OAuth 1.0 is sometimes referred to as "two-legged" (auth only between client and server) or "three-legged" (where a client requests data for a user of a third-party service).

One of the commonly agreed-upon disadvantages of OAuth1 was the lack of support it offers to non-browser based application clients. OAuth2 has different authorization work flows to address authorization initiated by native application clients. This was one of the main advantages OAuth2 has over OAuth1.

Effective July 1, 2021, OAuth 1.0a will no longer be certified.

A common implementation is to access APIs with the OAuth2 client credentials grant type. In this scenario, the API client uses its client ID and client secret to request an access token. The access token is then used on subsequent calls against the protected endpoints to authenticate the API client.

A real life example with a Web Page

The guys in Google made a webpage that contains some Javascript code. With this code they want to access, FROM THE WEB PAGE, to the list of the files in the Google Drive of an end-user. No server interaction is involved and this is the crucial part of the Implicit Grant flow.

While SAML is better to secure information, it makes sense to use OAuth when user experience is a priority, for example, on mobile devices or for quick logins and temporary access. OIDC was designed to be used with OAuth to provide single-sign-on (SSO) access to HTTPS endpoints.

Authenticate with UsernameToken

Enable the username and password security setting. Go to Setup | Security | Security Settings and find the setting under Username and Logins. Use the username and password to authenticate your SOAP calls in the header.

API consumers send API requests with a valid username and password to the API provider. The API provider then generates an encrypted token with the user's credentials, which is sent back to the consumer in response. API users can then use this token in subsequent API requests to authenticate themselves.

What is OAuth and how does it work? ›

OAuth is an open-standard authorization protocol or framework that provides applications the ability for “secure designated access.” For example, you can tell Facebook that it's OK for ESPN.com to access your profile or post updates to your timeline without having to give ESPN your Facebook password.

Compared to OAuth 1.0a user context authentication, OAuth 2.0 Bearer Token does not involve any Twitter user(s). This authentication is typically used for read-only access to publicly available information (for example, accessing public Tweets).

This is called the signature base string by the OAuth specification. To encode the HTTP method, base URL, and parameter string into a single string do as follows: Convert the HTTP Method to uppercase and set the output string equal to this value. Append the '&' character to the output string.

The Superiority of OAuth

Choosing OAuth over Basic Authentication equates to opting for a secure, encrypted locker over a simple lockbox for safeguarding valuables.
